types of hematoxylin stain
A. aluminum hematoxylin solution
B. iron hematoxylin
recommended for progressive staining of tissue
aluminum hematoxylin solution
produces good nuclear stain
aluminum hematoxylin solution
mordant of ammonium hematoxylin solution
potash aluminum
for tissues subjected to acid decalcification
Erlich’s hematoxylin
for tissues that have been become acidic during prolonged storage in formalin
Erlich’s hematoxylin
ripening agent of Erlich’s hematoxylin
sodium iodate
stabilizer of Erlich’s hematoxylin
glycerine
2 solutions of Erlich’s hematoxylin
- hematoxylin in absolute alcohol solution and heated
- aluminum potassium sulfate in distilled water + glycerin and heated
used for routine nuclear staining, exfoliative cytology, and sex chromosomes
Harris’ Hematoxylin
staining time for Harris’ Hematoxylin
5-20 mins
ripening agent for Harris’ Hematoxylin
Mercuric oxide
color of Harris hematoxylin when ripened with mercuric chloride
dark purple
stabilizer of Harris hematoxylin
4% glacial acetic acid
used in sequence with celestine blue
Cole’s heamtoxylin
ripening agent of Cole’s hematoxylin
Sodium perbonate
prior to use, it should be filtered before use for long periods
Cole’s hematoxylin
used to demonstrate the presence of cytoplasmic glycogen by special stain
Mayer’s hematoxylin
regressive and progressive staining
Meyer’s Hematoxylin
used for the demonstration of cytoplasmic glycogen
Mayer’s hematoxylin
ripening agent for Mayer’s hematoxylin
sodium iodate
used mainly for differential or regressive staining
iron hematoxylin
uses acid alcohol as differentiator
iron hematoxylin
types of iron hematoxylin
- weigert’s hematoxylin
- Heidenhain’s hematoxylin
- tungsten hematoxylin
- copper hematoxylin
made up of ferric chloride and standard iron hematoxylin

how many days will weigert’s hematoxylin remain active
1-2 days
It changes color from a deep blue-black violet, through violet, purple, brown, and yellowish brown
weigert’s hematoxylin
popular cytologic stain, especially for the study of mitosis
Heidenhain’s hematoxylin
recommended for mitochondria, muscle striation, chromatin, and myelin
